his, and came,
as soon as the young girl had sufficiently recovered her strength, to
see her, and endeavor to question her carefully.

She appeared ignorant of nearly everything relating to life, and,
although evidently intelligent, was wanting in many elementary ideas,
such as time, for instance. She had never been used to its division, and
the words signifying hours, days, months, and years were unknown to her.

Her eyes, accustomed to the night, were pained by the glare of the
electric discs; but in the dark her sight was wonderfully keen, the
pupil dilated in a remarkable manner, and she could see where to others
there appeared profound obscurity. It was certain that her brain had
never received any impression of the outer world, that her eyes had
never looked beyond the mine, and that these somber depths had been all
the world to her.

The poor girl probably knew not that there were a sun and stars, towns
and counties, a mighty universe composed of myriads of worlds. But
until she comprehended the significance of words at present conveying no
precise meaning to her, it was impossible to ascertain what she knew.

As to whether or not Nell had lived alone in the recesses of New
Aberfoyle, James Starr was obliged to remain uncertain; indeed, any
allusion to the subject excited evident alarm in the mind of this
strange girl. Either Nell could not or would not reply to questions, but
that some secret existed in connection with the place, which she could
have explained, was manifest.

"Should you like to stay with us? Should you like to go back to where we
found you?" asked James Starr.

"Oh, yes!" exclaimed the maiden, in answer to his first question; but a
cry of terror was all she seemed able to say to the second.

James Starr, as well as Simon and Harry Ford, could not help feeling
a certain amount of uneasiness with regard to this persistent silence.
They found it impossible to forget all that had appeared so inexplicable
at the time they made the discovery of the coal mine; and although that
was three years ago, and nothing new had happened, they always expected
some fresh attack on the part of the invisible enemy.

They resolved to explore the mysterious well, and did so, well armed
and in considerable numbers. But nothing suspicious was to be seen; the
shaft communicated with lower stages of the crypt, hollowed out in the
carboniferous bed.

Many a time did James Starr, Simon, and Harry talk over these
